The staging is again directed by Joe Mantello, who won the Tony for Best Direction for the earlier production. The dark musical explores the characters, motivations and social climates attached to U.S. presidential assassinations, attempted and realized. Cerveris played John Wilkes Booth and took home the Tony for Best Featured Actor in a Musical.

The production marked the Broadway debut of a property that already had a 1991 Off-Broadway staging and cast album. PS Classics ended up recording the Broadway cast, too, offering the most complete disc of the Americana-laced show set in the conceptual world of a carnival's shooting gallery, where scenes and people emerge from the shadows.

In addition to the Tony for Cerveris and Mantello, the 2004 production won Tonys for Best Revival of a Musical, Orchestrations (Michael Starobin) and Lighting Design (Jules Fisher and Peggy Eisenhauer). O'Hare was nominated as Featured Actor in a Musical for playing Charles Guiteau, killer of President Garfield.

The 2012 company also includes ensemble cast members from the original 2004 production, including Merwin Foard, Eamon Foley, Ken Krugman, Anne L. Nathan, Chris Peluso, Brandon Wardell and Sally Wilfert.

Todd Haimes, the artistic director of Roundabout, said in an earlier statement, "Roundabout's ongoing relationship with Stephen Sondheim has meant so much to this theatre over the years. Assassins was an incredibly proud moment for all of us, and I know that it will be thrilling to revisit Joe Mantello's brilliant production, especially with the original cast. We are so grateful to Mary Jo and Ted Shen, whose lead support allows us to present this reunion concert reading of Assassins and to raise important funds for Roundabout's Musical Theatre Program."

Here's how RTC characterizes the experience: "Assassins is the show that gives new meaning to the phrase 'killer musical.' With a stylish Stephen Sondheim score and a provocative book by John Weidman, Assassins brings to the stage a (shooting) gallery of some of history's most notorious players — the men and women who attempted to kill American Presidents. This striking work looks at the lives, loves and lunacy of nine American assassins, including John Wilkes Booth, John Hinckley, Lee Harvey Oswald and Lynette "Squeaky" Fromme. Both serious and satirical, the musical asks what hunger drove these people to their actions and what binds them all together. Is that drive what makes them quintessentially American?"

Roundabout's relationship with composer-lyricist Stephen Sondheim includes five Tony Award-nominated Sondheim revivals including Company (1995), Follies (2001), Assassins (2004), Pacific Overtures (2004) and Sunday in the Park with George (2008). In 2005, Roundabout honored Sondheim with the Jason Robards Award for Excellence in Theatre "for the indelible impact his life's work has made on the theatre world." In 2010, Roundabout's third Broadway home, the Stephen Sondheim Theatre, was named in his honor.

All proceeds benefit not-for-profit Roundabout Theatre Company and all its programs and activities.

Major support for the benefit performance of Assassins is provided by presenters Mary Jo and Ted Shen.
